WINDOW SCREEN Application filed November This invention relates to. window screens and similar devices where it is desired that a simple and compact construction be readily adapted for use to the ordinary sash arrangement of a window.

Heretofore it has been customary in temperate climates to apply window screens early in the spring season in order to prevent flies and other vermin from entering into rooms but permitting an abundance of air circulation. This has normally been done by applying the screen mesh or other net work to wood or metallic frames which are slidable or hingedly mounted upon the frame work of the window. It is an object of thisinvention to avoid such bulky frame work and to apply a compact construction to the frame of the window which will serve both as a screen arrangement in summer weather, and in winter weather when screens are not necessary, to serve as a wind deflector at the same time overcoming the necessity of removal and storage of the screen. The change in the device necessary to its use as a screen from that of a wind deflector or ventilator is comparatively slight.

Another object of this invention is to provide a window screen or similar device which is movable with the window in its sliding action to open or close and is attached thereto at or near its bottom edge so that when the window is in the closed position the screen is retracted and will not affect or obscure the light in any way.

A still further obj ectof this invention is to arrange the window screen with quickly detachable fastenings for securing it to a sash member of a window.

A still further object of this invention is to simplify the application of screens to a window so that a standard size screen apparatus maybe readily adjusted to accommodate or fit a particular sized window with a minimum of structural'changes.

Another object of this invention is to improve the operation of window screens and the like in which the screen is attached to one of the movable sash members and retracted from, or rewound upon, a springtensioned roller member having a housing 2, 1927. Serial No. 230,463.

for protecting it. By the use of simple and properly arranged endpieces the screen as a whole may be readily applied to-the frame work of a window with a minimum of efi'ort.

Further and more definite objects will appear in the following specification, claims and drawing in which' Figure 1 shows a window frame and sashto which is applied my improved form of' screen, part of the ventilating cover being broken away to show the internal Construction of'the screen roller, j

Referring now to the drawings and more particularly to Figures 1 and 2 the window frame construction 1 is mounted in the cus tomary way .upon the framework 2 of a house or similar enclosure. The windows 3 Figure 6 shows another detailed view in 1 and 4 slidably mounted with acids 5 for coun terbalancing their weight and maintaining them in fixed'position due to the frictional, engagement of the sashes 6 with the frameof the, window. Attached to the ledge 8 by means of thumb screws 9 or otherwise, is a cover or. ventilating enclosure l0.' Within this enclosurei's mounted for rotation. the roller 11 andthe idler 12, mounted at their ends and arranged in plates l3 'andll more particularly shown in Figure The cover lOmay'be made quickly detachable by .mak-

ing the holes l5'elongated of sufiicient siz e to. permit passage of the screws 9.

Theroller 11 is sprin'g-tension'ed appa ratus tobe described further on and is surroundedby the screen or'other' equivalent mater ial 16'.

The properhorizontal position of the screen with the window frame is maintained by the use 'of an idler' roller 12*about which the screen iswithd'rawn. This is preferably 1;)- cated at such points thatthescreen may be V directly'drawn in a perpendicular direction without undue. tension a'ndstrainl Thisvposi- Qtion maybe directly underneath the fastening of the ferruleor slightly to the right of that position as indicated in the sectionalview of I Figure 2', inasmuch as the. screen tendstogassume a sli htly bellyin 'ositi'on from the a a: P v

"In order to keep; the screen" 16 in proper alignment andprevent flapping or 'bellying at unsupported points along the edge, a 'strip21 and 22may be applied at the opposite edges of the window frameffor guiding the screen.

f The shapeof this stripis moreclearlyshown in Figure Sand if desired apiece of sheet 7 metallbent into an angular form as at 23 and 24 maybe usedas a backing piece for the screen 16, thereby providing slots between the 1 sheet metal pieces 28 and 24 and the wood strips 21 and22. Theproper clearance between these pieces can be adjusted as desired:

but sufficient should be providedso as to prevent undue binding on the screen. These strips and guide pieces maybe held in position by means of screwsor brads 25 and 26.

It is obvious ,thatthese pieces may'bezm'ade to fit'a'ny standard type of window "and from materials easily procured in the market.

The outer end of the shaft is supported I by the front'plate 3 5 having a hole throughv 150 whichthe shaft 28 projects and is loosely guidedthereby This. shaft has also. a fiat end portion 36ffor coacting with one of the l s end plates 14. Theother end: ofthe spring Slis secured by'means of a h1g3? struck out of the outer tubular covering member 38 fvvhich supports the end plate 36. This plate may be pushed over the roller 11' a sufficientdistance asto efiectively prevent sideways movement. Tlie other end offthe roller may be furnished tothe'userwi-thout attacl iment thereonan'd in order that it may be proper ioo ly fitt-e dito the locationwhere itisto be used.

The only other element necessary to be fitted to a particular width of windowis the 20 I outer casing or ventilating cover This may be cut off by; any su1table-.meansto fit by means o fyscrews'9. v j I 7 In connection with thiscoverm'mber 10 there may also be used a baflleor'backing plate 1 which is formedin the shape; indicated, inFig-ure 11 with ears 47 and 48-. "Thi'splate '46 will also have to'be'fitted' to the particular" v r filo size and tacked or otherwise secured-to the roll. The roller 12 is furnished in the form the location where it is to be used and screwed. i r to the window ledge aspreviouslydescribed w of the air.

window to which it is used and may be cut off as desired.

The end plates 13 and 14: are used to secure the whole assembly to the Window frame prior to applying the cover and the backing plate 46. different in construction as will be clear in connection with Figures 4 and 5 respectively; The end plate 13 is provided with a slot 60 in the horizontal direction and another slot in a vertical direction. There is also a hole 19 arranged at or near the center to accommodate the pin 40 of the roller 11. The slot for plate 46 extends downwardly to the point indicated at 50, leaving the upper end of the slot open to permit free access thereto. The plate 1 1 is substantially similar to the plate 13 except that the roller supports 44- and d3 extend from opposite sides of these plates making one of them, so far as theparts heretofore described are concerned, of substantially opposite construction. In addition to the slots of end plate 13 there is also provided in the plate '14 another slot 51 arran ed to ermit withdrawal and re )lacement of the roller 11 in a manner which is common to the shade roller art. If desired a similar slot may be provided in plate13 but this is not essential.

These plates 13 and 141 may be fired with 12 is adjusted by moving the plates 13 and 14: to the proper position so that the screen 16 will be easily withdrawn from the roller and coact with the rest of the window construction.

The upper part of the screen 16 being provided with a ferrule or binding strip 17 as previously explained and shown more clearly in Figure 10, is constructed to be readily attached or displaced from the lower part of the window frame. To permit such attachment the handles 54: and 55 may be used. A detail of these handles and the method of construction is shown in Figure 9. A slot 55 at the top of the ferrule is made so as to allow the handle 54 to be swung into a vertical position or a horizontal position, the horizontal position being shown more clearly in Figure 8.

The top portion 62 of the cover 10 is provided with a series of holes 61. These holes may be arranged in any manner or design so as to provide free access and circulation During the ordinary use of the screen in the summer time the binding strip 17 is attached to the window sash as shown in Figures 1 and 2. This attachment may be made by any suitable means, as previously described, and the window may be raised or These end plates are slightly lowered atzwill at the same time withdrawing or permitting retraction of the screen upon the roller 11 through the action of the spring 31. For use as a screen the cover plate A6 is positioned within the slot endingat 50 to serve both as a guide to the screen by preventing clamping or undue displacement of the screen adjacent this portion as well as to protect the screen and roller.

In'colder weather or when it is not desired to use the screen'the' protecting plate 16 may be withdrawn" from j the slot and the extending ends 58 formed by the extension of the ferrule 17 beyond the edge's of the "screen 16 may be positioned in these slots so that the screen will take the positionas indicated in Figure '8. When arranged 1n this position the window sash'maybe raised until it occupies the position at 59 where the air will be permittedto circulate as in-"' ,dicated by the arrows through a portion. of p the screen and through the holes 51 in an upward d1rect1on so as to cause no direct draught 1n the room in whlch the apparatus isus'ed. i 7

ltcan thus be seenfthat a convenient and compact arrangementisproyided which may 'be. readily fitted to difierentf widthsof window's' with a minimum of effort, that will provide-first a screening arrangement in warm weather and ventilating arrangement in cooler weather without inconvenience. Slight modifications can be made of the various parts as for instance the rear protection plate 16 may be done away with where only screening is desired. In order to retain the cover 10 more firmly in position the end may be extended out to overlap the "end plates 13 and 141- throughout the extent of the perpendicular portion, while the horizontal portion may be made to fit closely within theconfines of the end plates 13 and 14:. A series of struck-up portions maybe made to serve as a guide 'for the side edges of the horizontal portion if desired, but

these are not shown, it being understood that any well known means for securing this por= tion but consistent with the easy replaceability of the cover may be used. Also this cover plate may be attached directly to the end pieces 13 and 14; by any convenient quickly detachable means. The apparatus may also be readily installed at the top of the window frame as well as the bottom with equal efliclency.
